Pumablock Mortero adhesivo

Composition

Product formulated with high-strength cement, selected aggregates, and special additives.

Features and applications

• Masonry works of cellular concrete block.
• Thixotropic, easy to apply both horizontally and vertically.
• Permeable to water vapor and impermeable to rain.
• Hardens without significant shrinkage, allowing for perfect adhesion of the blocks.

Substrates

The construction elements must be dimensionally stable and solid, free from loose parts, dust, oils, and any other substances that could affect adhesion.

Instructions for use

• Add 5-6 liters of water per bag and mix manually or mechanically until a homogeneous and workable consistency is achieved.
• Lift the concrete blocks using special trowels of the same width as the wall. Apply a continuous layer approximately 3 mm thick, place the blocks, and gently tap them with a rubber mallet to ensure proper seating. This method achieves a uniform and continuous layer with a consistent thickness between 1.5 mm and 2 mm.
• To lay the next course of blocks, wait until the adhesive of the previous course has completely dried.
• Before placing each course of blocks, it is essential to verify the perfect leveling of the wall both longitudinally and transversely. If necessary, make corrections by sanding and removing dust and loose parts.
• Next, remove any mortar that oozes from the joints and level these joints as soon as possible.
• The vertical faces of interlocking blocks will not receive Pumablock adhesive mortar. However, a continuous layer of adhesive mortar should be applied at junctions between blocks with smooth faces, at right-angle joints, and at connections between cut blocks.
   

Cautions and recommendations

• Do not apply below 5°C or above 30°C.
• Do not apply in the presence of frost, rain, strong winds, or direct sunlight.
• In extreme weather conditions (high wind or high temperatures), drying occurs faster than normal.
• It is important not to mix Pumablock adhesive mortar with plaster, cement, sand or other construction materials.
